To if/ZZ whom it may concern):

Be it known that I, SYLvEsTER LOGAN, a citizenof the United States,residing at Emlenton, in the county of Venango and State ofPennsylvania, have invented a new and `useful Reversing Mechanism, ofwhich the following is a specification.

My invention relates to mechanism espe'- cially adapted to engines,although capable of being applied to all kinds of machineryin which itmay be necessary or desirable to reverse the motion with ease andrapidity, the object being to improve the construction and operation ofsuch reversing mechanism.

Iith this object in View myinvention con sists in the improvedconstruction, arrangement, and combination of parts, hereinafter fullydescribed and afterward specifically pointed out in the appended claims.

In order to enable others skilled in the art to which my invention mostnearly appertains to make and use the same, I will now proceed todescribe its construction and operation, having reference to theaccompanying drawings, forming part of this specification, in which-Figure l is a view in side elevation of so much of an engine as isnecessary to illustrate the application of my invention thereto. Fig. 2is a vertical sectional view taken on the plane indicated by the brokenline 2 2 of Fig. l. Fig. 3 is a detail view of the eX- panding ring ofclutch.

Referring to the drawings by letters, A indicates the frame of anengine, in which are journaled the usual driving-shaft B and a parallelcounter-shaft C, the main shaft carrying fiy-wheelsD D and being gearedto the counter-shaft by keyed gear-wheels E F, so that the two shaftsrun in opposite directions.

G and H indicate pulleys loosely mounted on shafts B and C,respectively, and G H clutches by which these wheels may be clutched totheir respective shafts when desired, said clutches being provided witha single operating-lever I, pivoted at I to a fixed part of the engine,so that when the pulley G is clutched to the shaft A the pulley H willbe loose on shaft C, and vice versa.

J indicates an idler-pulley mounted on a shaft J', journaled in a slot Kin the frame of the engine, said slot being` horizontal and in a linecutting centrally through-the space between pulleys G and H.

L indicates a belt engaging around pulleys vG H and the idler-pulley Jand extending to any shaft which it may be desired to drive, such as aline-shaft or the shaft of any kind of machinery, the purpose of theidler being to serve as a belt-tightener and to cause the belt to lap agreater portion of the peripheries of the pulleys G and H.

The operation of myinvention as described may be explained as follows:The engine being` started, shafts B and C, as before explained, willrotate inopposite directionssay the shaft B to the right and the shaft Cto the left--and obviously either of the pulleys G and II when clutchedto its shaft will rotate with it. Should it be desired to drive a shaftover which the belt engages toV the right, the pulley G will be clutchedto shaft B and will become the driving-pulley, while the pulley H, looseon shaft C, will act as an idler, and to reverse the motion ofthevdriven shaft the lever I will be thrown to the left to the positionshown in Fig. 2, the iirst part of said movement unclutching pulley Gfrom shaft B and the last part clutching pulley H to shaft C, wherebyI-I becomes the driving-pulley and G an idler causing the driven shaftto be reversed and rotated to the left.

While I have illustrated my invention as applied to an ordinary type ofgas-engine, it will be readily understood that it may be applied to anyother class of engines and to any parallel re versely-driven shafts,and, further, that the pulleys and belt may be dispensed With and cog orother well-known form of driving-gearsubstituted.

While I have illustrated and described what I consider to be efficientmeans for carrying Having thus fully described my invention,-

what I claim as new, and desire to secure by Letters Patent of theUnited States, is

1. The combination with two parallel shafts driven in oppositedirections, ofa pulley loose IOO on each shaft, a belt engaging aroundboth pulleys, a lever and clutch mechanism arranged to loosen one pulleyand clutch the other by a single movement ofthe lever, substantially asdescribed.

2. The combination With two parallel shafts driven in oppositedirections, of a pulley loose on each shaft, a belt engaging around bothpulleys, an idler mounted in a line extending centrally between thepulleys and encircled by the belt, a lever and clutch mechanism arrangedto loosen one pulley and clutch the other by a single movement of thelever, substantially as described.

3. The ,combination With the frame of an engine, of a main shaft and aparallel counter-shaft journaled in the frame and driven SYLVESTERLOGAN.
